**Start training your ears to understand what you hear.** In Part 1 of *The Basics of Ear Training*, you'll learn the three main functions of harmony—**Tonic, Subdominant, and Dominant**—and how each creates a different sense of tension and resolution. You'll begin developing the ability to recognize these functions by ear, helping you better understand chord progressions, anticipate where the music is going, and rely less on guesswork when playing.
